When using sand as the filter material, it is recommended to backwash the filter system a minimum of 2-4 times per month. Backwashing helps to clean the sand and maintain the efficiency of the filtration process. Each backwash typically uses between 180 and 240 liters of water, so it's important to consider water usage when choosing sand as the filter material.
